' IMPROVEMENT IN CARBU RETERS.

. Specification forming part of Letters Patent No. 203,371, dated May '7, 1878; application filed l March 29, 1878.

To all tuhomtt may concerne Be it known that I, JOSIAH REED, of Troy,

have invented certain new and useful Improvements in Oarbureters and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to 'make and use the same, reference being had to the accompanying drawings, andto letters of reference marked thereon, which form a part of this specification, and in which- Figure 1 represents a side elevation of my improved earbureter. Fig. 2 is a plan view, partly insection, of the same, with the airvalve swung around to show it more fully. Fig. 3, Sheet 2, is a vertical section thereof, with the air-valve also shifted; and Fig. 4 is a detached view of the same.

Corresponding parts in the several figures are denoted by like letters.

This invention appertains to an improvement in carbureters, forthe production of carbureted air for illuminating purposes from gasoline and air, or for the enriching of ordinary coalgas. p 7. The chambers A A A are made preferably of galvanized iron, or any other suitable material, about eight feet long, eight inches wide,

' and six inches deep, or in similar proportions.

B B B are spaces between the chambers or cells, about four inches in width, which receive interveninglayers of hydraulic cement. These spaces are filled with cement in order to in crease the extent of outside surface of contact of the cells with the surrounding earth, whose temperature is always, at a suitable depth, greater than the temperature of the .cells, wherein cold or low temperature is caused by the rapid-evaporation of the gasoline contained therein. The cement employed is the hardest, and consequently the most durable, known to the art, wherefore a comparatively thin layer thereof may be employed, and its conducting capacity thereby increased, and it is rendered a better conductor by the hydrocarj but little or no surface of contact, and could not receive much heat from the surrounding in the county of Miami and State of Ohio,

earth to counteractthe cooling tendency that invariably accompanies rapid evaporation.

The object of my invention is to provide a earbureter of such construction as to give a large amount of evaporating-surface, combined with the largest possible amount of surface of contact with the surrounding earth. It stands about in the same relation to the ordinary tubshaped earbureter that a flueboiler does to a boiler of cylindrical shape.

The cells may be varied in number from two to four, or more, to suit the capacity of the earbureter or machine, and are thoroughly 1 painted or coated with asphaltum. These cells aresupplied with a kinked, curly, fibrous filling or material, B B, made from picked sisal or sea-grass rope, whichincreases the amount of evaporating-surface. This material is particularly suited to this purpose, as it is light, elastic, and'does not pack or gum, and, while it acts asan absorbent, it does not obstruct the free passage of the gas or air. a

In locating the cells A A, an excavation or hole is made in the ground at the desired point, say, about eight or nine feet deep, according to the nature of the soil and climate, and of sufficient size in its other dimensions to provide about sixteen inches space around the earbureter or machine. A vault, A of brick or masonry, is built in the excavation, with a wall of about fourinches in thickness, and the intervening space between the vault and earbureter is filled with a casing of hydraulic cement, which is about thesame thickness as the wall of the vaultabout four inches-and high enough to receive plank placed thereon to support the superincumbent weight of earth until the cement hardens.

Before the placing of the plank in position, above alluded to,the bottom of the excavation orhole is treated with a coating or floor of cement, which is made perfectly level. Upon this floor of cement islaida second and finer course of cement, which is troweled down until solid. i

The earbureter is now placed in position upon the cement floor of the excavation. Cement is filled in around and upon itscells and in the spaces between the same,'to form a casing, B for the carbureter of about four inches in thickness, and thus completely incase the cells in a strong inclosure, which serves as a carrier or conductor of heat between the earth and the contained liquid.

It will be further observed that by this inclosure of cement excluding moisture the cells will be protected from oxidation; or even, in the event of that, the hardened-cement inclosure will have formed cells though the iron or metal may have become oxidized. Further, the gasoline or liquid will be prevented from escaping through leakage, and a uniformity of temperature be maintained.

Connected to one of the cells is a' fillingpipe, I), to which is connected a second pipe, 0, having the burner, and provided with a stopcock or cut-off, d.

e is another pipe, extending from the burner-pipe 0, and connecting with another cell, or at a point communicating with two adjacent cells, and having a cut-off, f, the object of which is to regulate the quality of the gas to be fed to the burner, as it is obvious that the nearer the gas is taken from the supplyingpoint the less vapor of gasoline it will contain, and vice versa. 9 is a vent-tube, which, of course, is opened when filling the carburetor.

E is a water-tank, up through the bottom of which is passed a pipe, h, connected to a pipe, 7L leading into one of the cells, and having a waste-cock, 71. for the withdrawal of water that may have accidentally entered it. F is the air holder or receptacle, suspended in the tank E by a weighted chain'or cord, f, passing over a pulley, s, journaled in the beam or cross-piece h, supported upon uprights i i, that may be secured in position to the tank E. This receptacle is for holding atmospheric air, which is fed to the cellsAA through the pipe h and the pipe h, leading from it to said cells. The supply of air may be regulated by a cock, j, to vary the brilliancy of the light. I k is a crank, suitably journaled in position, and connected to the air-receptacle F by a cord, Z, or its equivalent, to enable the said receptacle to be returned to its elevated position after the discharge of the air, when, by the opening of its valve, it is refilled with air. an is a valve, fitted air-tight upon the under side of the top of the receptacle F, so as to cover an opening therein, and connected to pendants upon the inside of the said receptacle by a lever, art.

To the upper side of the valve on is secured its stern m pivoted to one arm of a bell-crank, 0, fulcrumed at its angle to the top of the receptacle F. This stem is threaded and connected to the valve by a clevis, to permit of the increasing or diminishing of its leverage. To one arm of this crank or lever is attached the cord or chain f, and to that arm to which the stem of the valve is attached is fastened the free end of the cord or chain Z of the crank k.

. It will be. seen as the air-receptacle is descending its valve m will be kept closed by the weighted cord orchain f and the pressure of I the confined atmospheric air, and its air thus caused to escape through the pipe it into the cells, the proper channel to receive'it. Upon elevating the said receptacle by the crank k, I

lever of the valve m is pivoted. The outer cir' cumference of the neck 1) is provided with a screw thread, to permit of the adjustment thereto of a threaded ring or nut, g, by which it is locked in place, as clearly shown.

This arrangement renders'the valve attach ment easily connected and disconnected, and it may be manufactured separately from the air-receptacle to which it is applied.

Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, is-

1. In a carbureter, the cells A, with vent g, cement B, and adjusting-pipe 0, with cut-offj' and eduction-pipe c, substantially as shown, and for the purpose described.

2. The cells A A, as receptacles for gasoline, sisal hemp, and, for the passage of air, inclosed in a casing of cement, B and vault A in combination with adjusting-pipe e, eduction-pipe c, tank E, and air-receptacle F, substantially as shown, and for the purpose specified.

8. The tank E and air-holder F, having an automatic valve, m, weighted cord or chain f, cord 1, and crank K, connected to said valve, in combination with the carburetor A A, connected by pipe h to said air-holder F, substantially as and for the purpose set forth.

4. The automatic valve consisting of the valve-disk m, provided with a lever, m and stem m in combination with the weighted cord or chain f, chain or cord 1, and crank K, substantially as shown and described.

5. The combination of adjusting-pipe e, having cut-off f, eduction-pipe 0, cells A A, vent g, sisal-hemp B tank E, and air-receptacle F,

substantially as shown, and for the purposedescribed.

In testimony that I claim the foregoing as my own I attix my signature in presence of two witnesses.

JOSIAH REED.
